JULIUS \VITT, OF LOS ANGELES, CALIFORNIA.

MOTOR FOR VELOCIPEDES.

SPECIFICATION forming part of Letters Patent No. 361,341, dated April 19, 1887.

Application filed February 5, 1867. Serial No. 226,612. (No model.)

10 ing reciprocating motion into circular motion and applying such-motion in propelling roadwagons and other machinery.

The object of myinvention is to produce a machine by means of which the reciprocating 1 movement of a lever will operate to revolve the wheels of a road-wagon to propel it. I accomplish this by means of the device described herein, and illustrated in the accompanying drawings, in which Figure 1 is a front elevation of my improved mechanical movement as it appears when applied to a road-wagon, the body of the wagon being cut'in section on line 2 z, Fig. 2. Fig. 2 is a vertical mid-section of a road-wagon pro- Line 00, Fig. 1, indicates the line of section. Fig. 3 is a vertical mid-section of my improved mechanical movement on line y Fig. 4. Fig. 4 is a plan view of my improved mechanical omovement. Fig. 5 is a side elevation of the hand-lever which operates the motor. is a plan view of the shifting frame 0.

In a road-wagon to be operated by hand it is desirable that the machinery be so arranged Fig. 6

that the operating mechanism can be thrown out of gear at pleasure to allow the wheels to revolve without operating the motor. It is also desirable that the operating mechanism be so constructed and arranged that the move- 0 ment of the operating-lever in either direct-ion will serve to propel the machine.

In theaccompanying drawings, A is the hand-lever by which the motor is operated. This lever is rigidly mounted upon a revolu- 5 ble shaft, B, upon which the shifting frame 0 is journaled,so as to be free to vibrate thereon,

and also to slide along the length thereof.

Upon the lower end of the shifting frame 0,

I provide a broad segmental cog, D, forming the arc of a circle having the shaft B for its center.

the shaft E, upon which are mounted two pinions, F and G. The pinion F is fixed upon the shaft, and the pinion G is loose and revolves freely. A crown-wheel, H, is suitablyv mounted in such a manner as to engage with each of the pinions, so that when one pinion is revolved in one direction the other pinion will be caused to revolve in the opposite direction.

The shifting frame 0 is provided upon each side, at the top, with guide-bars I I, which are parallel with each other and stand at an angle with the shaft B. The lower end of the shifting frame is provided with two corresponding guide-bars, J J, which form an angle with the shaft B, corresponding to the angle between the shaft and the bars I 1, except that the angle is in the opposite direction, as shown in Fig. 6. V

Upon the front and rear of the lever A, at such points thereon as to come in contact with the guidebars I I and J J as the lever is vibrated, are mounted friction-rollers L L L L. It will be observed that when the upper end of the lever A is moved back the roller L will press upon the guide-bar I, and the illclination of the bar will tend to cause the frame to slip along the shaft to allow the frictionroller to run into the corner of the frame farthest from the shaft B. The inclination of the lower guide-bar, J, upon the opposite side of the frame tends, in the same manner, to slip the frame in the same direction when the friclion-roller L strikes upon it, so that the guides I and J and the rollers L and L operate simultaneously to force the shifting frame to one side, as shown in Fig. 3, when the lever A is thrown back. When the lever is thrown forward, the rollers L L operate upon the guide- .bars I and J and shift the frame to the other side, as shown in Fig. 4.

In order to more easily shift the frame 0, I provide the guide-cylinder K, which has openings M M cut into its upper and lower. side, through which the shifting frame passes. The diagonally opposed corners of each opening correspond in shape, two being rectangular and two being curved. The curved corners are upon the same side with the corner of the frame 0 which is nearest the shaft B, as will be seen by reference to Fig. 4:.

N N are the angular corners, and O O the ICC curved corners. Friction -rollers P are mounted upon the corners of the shifting frame, which project toward the curved corners of the opening N of the cylinder, so that when the frame is vibrated by the lever the rollers P will strike upon the curved edges 0 0 both at the top and the bottom. The rollers will slip along the curved edges, and thus assist in moving the shifting frame from one side of the opening to the other.

The operation of the machine is as follows: The lever Av is pushed forward, thus causing the upper roller on one side of the lever and the lower roller on the other side of the lever to come into contact with the guide-bars of the shifting frame, and also causing the shifting frame to swing with the lever until the rollers P come into contact with the curved edges of the guide-cylinder. The combined action of the rollers and guides causes the shifting frame to slip along the shaft 13, thus carrying the segmental cog D into contact with either the fixed pinion F or the loose pinion G, which it causes to revolve. Vhen the cog D meshes with the fixed pinion F, the shaft E is rotated, thus rotating the wheels Q and propelling the wagon. Vhen the cog D meshes with the loose pinion G, it causes G to revolve, thus rotating the crown-wheel H, which rotates the pinion F and the shaft E.

The cog D is of such width and the piuions F and G are at such distance apart that the cog clears one pinion before it meshes with the other as it is shifted back and forth. The cog D, as it is swung back and forth by the lever, is shifted first to mesh with the fixed pinion and then with the loose one, rotating them in opposite directions; but theniotion is conducted from the loose pinion to the fixed one by the erownwvheel H, thereby driving the fixed pulley in the same direction given it by the cog D. Thus a continuous rotary motion is given the shaft E by the reciprocating vibratory motion of the lever.

Sufficient play is allowed for the vibration of the frame to permit the segmental cog to be thrown so far back or forward as to be with drawn from contact with either pinion at the time it is being shifted from one pinion to the other. This allows the wheels to revolve while the lever is held stationary at its farthest limit of motion, either forward or back.

In applying my motor to a road-wagon I provide an additional lever, B, and eonneetit with the lever A by an arm, S, pivoted to such lever.

Now, having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination of the lever A, shaft B, shifting frame 0, rollers L L L L and P P P P, guides I I J J, segmental cog D, fixed pinion F, loose pinion G, crown-wheel H, and shaft E.

2. In a device, substantially such as set forth,for converting reciprocating motion into rotary motion, the combination of the laterally'shifting vibratory segmental cog D, the shaft E, fixed pinion F, and loose pinion G, mounted on such shaft, a crown-wheel meshing with such pinions, and mechanism to shift the cog from one pinion to the other, substantially as and for the purpose set forth.

In a mechanical movement substantially such as described, the device for shifting the segmental cog, consisting, as set forth, of the combination of the lever A, provided with friction-rollers L L L L, the shaft 13, frame 0, mounted upon the shaft B so as to slip along the length thereof, and guides I I J J, attached to the frame at an angle with the shaft B, as set forth, whereby the impact of the rollers upon the guides tends to cause the frame to slip along the shaft, as set forth.

4. In a mechanical movement substantially as set forth, the device for shifting the segmental cog, consisting of the con'ibination of the frame C, friction-rollers P P P P, and curved guides O O O O. t

In a mechanical movement substantially such as set forth, the combination of the lever A, friction-rollers L L L" 1/, frame 0, friction rollers P P P P, guides I 1 J J O O O O, and the shaft B.
